Detail waterproofing is important for the protection of the roof  in roof structure.Complex and tricky details are some of the classic weak points in roof structures. Wall-floor connections, Flashings and 90o angles, Lightdomes, Rooflights, Chimneys, Pipes, Siphons and Gutters are normally causing most problems in roof waterproofing. MARIS POLYMERS offers the MARISEAL® DETAIL, a liquid Polyurethane detail waterproofing system with long-term protection for simple, detailed or complicated roof detail structures.

The MARISEAL® DETAIL is a technologically advanced, thixotropic and fiber-reinforced, liquid polyurethane waterproofing coating that offers easy application, full certifications, and most importantly guaranteed long lasting results. It can be used for new flat roof construction but also for repair or renewal.
